Struct SerdeDFA

pub struct SerdeDFA<'data> { /* private fields */ }

A serde-compatible version of regex_automata::dfa::sparse::DFA.

This does not implement serde::Deserialize directly, as binary deserialization is not supported in big-endian platforms. Self::maybe_deserialize can be used to deserialize to Option<SerdeDFA>.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.

Implementations

impl<'data> SerdeDFA<'data>

pub fn maybe_deserialize<'de, D>( deserializer: D, ) -> Result<Option<SerdeDFA<'data>>, <D as Deserializer<'de>>::Error>

where 'de: 'data, D: Deserializer<'de>,

Deserializes to Option<Self>. Will return None for non-human-readable serialization formats on big-endian systems, as regex_automata serialization is endian-sensitive.

impl<'data> SerdeDFA<'data>

pub const unsafe fn from_dfa_bytes_unchecked( dfa_bytes: &'data [u8], ) -> SerdeDFA<'data>

Creates a SerdeDFA from raw bytes. Used internally by databake.

Safety

dfa_bytes has to be a valid DFA (regex_automata::dfa::sparse::DFA::from_bytes(dfa_bytes).is_ok())

pub fn deref(&'data self) -> DFA<&'data [u8]>

Returns the represented DFA

Trait Implementations

impl<'data> Clone for SerdeDFA<'data>

fn clone(&self) -> SerdeDFA<'data>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'data> Debug for SerdeDFA<'data>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for SerdeDFA<'_>

fn eq(&self, other: &SerdeDFA<'_>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Yokeable<'a> for SerdeDFA<'static>

type Output = SerdeDFA<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a <SerdeDFA<'static> as Yokeable<'a>>::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> <SerdeDFA<'static> as Yokeable<'a>>::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make( this: <SerdeDFA<'static> as Yokeable<'a>>::Output, ) -> SerdeDFA<'static>

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut <SerdeDFA<'static> as Yokeable<'a>>::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

impl<'zf, 'zf_inner> ZeroFrom<'zf, SerdeDFA<'zf_inner>> for SerdeDFA<'zf>

fn zero_from(this: &'zf SerdeDFA<'zf_inner>) -> SerdeDFA<'zf>

Clone the other C into a struct that may retain references into C.
